Determination of the Chemical Oxygen Demand Using a Cu‐Au Anisotropic Nanoalloy‐Modified Screen‐Printed Electrode: A Sustainable and Sensitive Solution

open access: yesChemElectroChem, EarlyView.
A novel, non‐enzymatic electrochemical sensor employing gold‐copper nano‐brambles enables rapid, accurate, and chloride‐tolerant chemical oxygen demand (COD) detection. Demonstrating high sensitivity and excellent performance in real wastewater samples, this portable platform offers a sustainable and efficient alternative for on‐site COD monitoring in ...

Terrestrial vertebrates as surrogates for selecting conservation areas in a biodiversity hotspot in Mexico

open access: yesConservation Science and Practice, EarlyView., 2019
Systematic conservation planning (SCP) identifies priority areas for biodiversity conservation using surrogates for adequate representation of biodiversity content. The use of multiple well‐known taxonomic groups rather than single ones as a surrogate set is expected to enable a better representation of most important biodiversity constituents in ...

Chemical Evolution of Early Macromolecules: From Prebiotic Oligopeptides to Self‐Organizing Biosystems via Amyloid Formation

open access: yesChemistry – A European Journal, EarlyView.
APR‐A, an aggregation‐prone oligopeptide, can convert into APR‐B through distinct mutational pathways—some exclusively forming insoluble amyloid‐like peptides, others yielding water‐soluble, non‐aggregating monomers. These orthogonal pathways in chemical evolution may have driven macromolecular assembly under prebiotic Earth conditions, potentially ...

A Flexible, Perfluorinated Analogue of Aluminum Fumarate Metal‐Organic Framework

open access: yesChemistry – A European Journal, Accepted Article.
Herein we report the synthesis of Al‐TFS, a novel aluminum metal‐organic framework (MOF) based on tetrafluorosuccinic acid (H2TFS), of formula Al(OH)(TFS)·1.5H2O, introducing a new member to the family of perfluorinated MOFs. The structure of the MOF, solved ab‐initio from laboratory powder X‐ray diffraction data, displays structural analogies with ...

Singlet, Doublet, and Triplet Emissions of Diarylamine‐Modified Bismuth Pincer Complexes

open access: yesChemistry – A European Journal, EarlyView.
Reversibly oxidizable diarylamine‐modified phenyl‐bis(dimethylaminomethyl) pincer bismuth complexes and their radical cations emit via excited singlet and triplet or doublet excited states at 77 K in solvent matrices, in solution, or in the solid state.
